This paper describes the latest developments in the Worcester Polytechnic Institute (WPI) Precision Personnel Location (PPL) system. An RF-based system with inertial sensor supplementation is being developed for tracking of first responders and other personnel in indoor environments. The system assumes no existing infrastructure, no pre-characterization of the area of operation and is designed for...
We present an FPGA-based co-processor for accelerating computations associated with Singular Value Array Reconciliation Tomography (SART), a recently developed method for RF source localization. The co-processor allows this relatively complex computational task to be performed using less hardware and less power than would be required by a microprocessor-based computing cluster with comparable throughput...
To save life, casualty care requires that trauma injuries are accurately and expeditiously assessed in the field. This paper describes the initial bench testing of a wireless wearable pulse oximeter developed based on a small forehead mounted sensor. The battery operated device employs a lightweight optical reflectance sensor and incorporates an annular photodetector to reduce power consumption. The...
